I would like to help the owners of a pub (based in Milan, Italy) to decrease the environmental impact of the waste they produce.
My intent is to make them buy the same food content (especially drinks) by choosing the products with the most sustainable packaging.
they gave me the list of products they buy, with some alternatives for each food content type.
packaging content recycling simbol volume (l)
bottle tonic water triangle PETE 1 0.10
bottle lemon soda triangle PETE 2 0.10
bottle coca cola triangle PETE 3 0.20
bottle coca cola triangle PETE 4 0.15
tin fanta Exagon ALU 0.033
tin coca cola Trangle ALU 41 0.034
tin lemon soda Exagon ALU 0.035
tin chinotto circle ALU 0.036
Based on this data, how could I set up the analysis?
What's the best way to estimate what is the impact of a packaging on the recycling system of my town, and on the environment?
